A Material Safety Data Sheet (MSDS) is a written document that provides product users and emergency personnel with information and procedures needed for handling and working with chemicals.
Some chemicals shouldn't be mixed together. In fact, these chemicals shouldn't even be stored near each other on the chance that an accident could occur and the chemicals could react.
Some rules are NOT made to be broken. That is true of the rules used in a chemistry lab. They are really, truly for your safety and not your humiliation.
